We combine both U.S. and international equity to provide exposure to about 99% of the public market and contain all market caps, investment styles, sectors, and developed and emerging markets, including global real estate. We do have a home bias, and our research has shown that allocations of 30% to 40% to international stocks have provided more than 95% of the benefit of full market-cap diversification.

Strategic asset allocation
Our philosophy rests on the evidence that a sound investment strategy starts with an asset mix built on reasonable expectations for risk and return and uses globally diversified market-cap-weighted investments to help avoid exposure to unnecessary risks.
The strategic approach remains a key investment principle underlying Vanguard Target Retirement Funds. It has proven to drive more than 90% of a portfolio’s long-term variability1 and remains as effective as ever in helping participants seek lifelong financial well-being.

We carefully evaluate asset classes and strategies through a TDF-specific lens and exclude those that add volatility without adequate compensation in return or that fail to meet the criteria below.
- Investor suitability: for the broadest swath of participants, appropriate as a QDIA and for all industries.
- Investment value: cost, simplicity, transparency, liquidity.
- Portfolio construction: improved diversification, enhanced return, reduced risk.
- Impact on outcomes: materially improve long-term probability of retirement success.

U.S. bonds
We combine broad exposure to nominal U.S. investment-grade bonds with the safety and liquidity of government and short-duration bonds to provide diversification to the equity exposure.
Why do Vanguard Target Retirement strategies currently exclude high-yield bonds? They represent a small portion of the taxable U.S. bond market, and our research shows that overweighting them compared with the market has increased overall portfolio volatility and downside risk.
International bonds
Unlike most TDFs, we also include an allocation to international investment-grade bonds. This gives our TDF investors exposure to a greater number of securities (7,000 plus), countries (40 plus), yield curves, and economic and inflation environments. Importantly, the factors that drive international bond prices are relatively uncorrelated to those that drive U.S. bond prices.
Our international fixed income assets are hedged back to the U.S. dollar, which minimizes the volatility of global currency fluctuations. Our research has shown that these fluctuations, when unhedged, account for a significant portion of the overall volatility of the asset class. We believe our hedging is critical to maintaining the risk and return properties of the asset class.

Inflation protection
As participants approach the drawdown phase, they need more inflation protection without introducing more volatility into their portfolios. Five years before the target retirement year, our TDFs start incorporating short-term Treasury inflation-protected securities (TIPS) at age 60.
Our research shows that short-term TIPS provide a hedge against unexpected inflation without the volatility of other asset classes such as commodities, overweighting REITs, or broader TIPS portfolios with average maturities in the intermediate-term range.

Static tilts
This strategy tilts the portfolio allocation away from market-cap weight. Equity tilts are often made by size, style, sector, or location, and fixed income tilts are frequently based on credit quality, duration, or location.
These tilts may have provided outperformance during certain periods historically, but they tend to be inconsistent throughout a full market cycle, and their long-term effectiveness is uncertain. In fact, most size and style tilts found in TDFs have been small in nature and have had no discernable impact on the long-run probabilities of retirement success.
Tactical
In theory, tactically adjusting long-term portfolios, such as TDFs, during periods of market turbulence may seem like a good idea. However, research consistently shows that tactical moves—which amount to market timing—are counterproductive over time.
We believe the most prudent way for TDFs to achieve their long-term objective of allowing investors to retire with some assurance of sufficient lifetime income is to start with an asset mix built on reasonable expectations for risk and return and use diversified investments to help avoid exposure to unnecessary risks. This strategic approach should remove the temptation to make tactical adjustments when markets are roiling.

The Income Trust/Fund and the Income and Growth Trust have fixed investment allocations and are designed for investors who are already retired. An investment in a Target Retirement Trust or Fund is not guaranteed at any time, including on or after the target date.
Investments in bonds are subject to interest rate, credit, and inflation risk. Investments in stocks or bonds issued by non-U.S. companies are subject to risks including country/regional risk and currency risk.
